The Whitter Family from England

I am new to family tree research and would appreciate any help!

The WHITTER family I am trying to trace come from the Wigan/Manchester area England.

My Mother, Jean born 1934 was an only child and both her parents died young. Her Mother Doris WEIR born Abt. 1903 died 1935 aged 31 years. Her father Thomas WHITTER born Abt. 1903 died 1937 aged 33 years. My mother was raised by her Great Aunt Margaret WHITTER and her Grand-father Joseph WHITTER born Abt 1880 died 1964 aged 84 years. Grand-mother we think was called Mary born Abt.1884 died 1934.
